Abstract
Abstract There is disclosed an optical system for reading light-activatable marks on a record medium. The system includes a coupling for connecting a light bulb and a light conductor which allows for relative movement between the light bulb and the light conductor while maintaining light transmitting contact therebetween.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
An optical system including a light bulb, a light conductor for conducting light from the bulb to a remote location, means for holding the light conductor against the bulb, and wherein the holding means includes a resilient pad extending partially about the bulb and a member in gripping relation with the light conductor and urging the resilient pad to hold the conductor and the bulb in light transmitting relationship.
Claim 2
Dependent Claim
69 words
An optical system including a light bulb, a light conductor for conducting light from the bulb to a remote location, means for holding the light conductor against the bulb, and wherein the holding means includes a resilient pad extending partially about the bulb and a member in gripping relation with the light conductor and urging the resilient pad to hold the conductor and the bulb in light transmitting relationship.
Claim 3
Dependent Claim
61 words
An optical system as defined in claim 1, wherein the resilient pad is U-shaped and the member includes a U-shaped clip wrapped about the pad, wherein the light conductor has a pair of shoulders, the clip having opposed ends providing flanges engaged with the shoulders, the resilient pad being under slight compression to urge the light conductor against the light bulb.
Claim 4
Dependent Claim
98 words
An optical system, comprising: a light bulb including an elongate ionization tube and a light conductor for conducting light from the tube to a remote location, the light conductor having an end portion, the light conductor being positioned generally laterally with respect to a side of the tube, the end portion of the light conductor being positioned against and in contact with the outside of the tube, and resilient means extending at least partially about the ionization tube and including a connector for removably holding the ionization tube and the light conductor resiliently in contact with each other.
Claim 5
Dependent Claim
98 words
An optical system, comprising: a light bulb including an elongate ionization tube and a light conductor for conducting light from the tube to a remote location, the light conductor having an end portion, the light conductor being positioned generally laterally with respect to a side of the tube, the end portion of the light conductor being positioned against and in contact with the outside of the tube, and resilient means extending at least partially about the ionization tube and including a connector for removably holding the ionization tube and the light conductor resiliently in contact with each other.
Claim 6
Dependent Claim
39 words
An optical system as defined in either claim 1 or claim 3, wherein the light bulb comprises an elongate ionization tube having an opaque portion and a light transmitting portion through which light is transmitted to the light conductor.
Claim 7
Dependent Claim
46 words
An optical system as defined in either claim 1 or claim 3, wherein the light conductor includes a one-piece light rod and a straight filter between the light rod and the bulb, wherein the light rod has a straight end in contact with the straight filter.
Claim 8
Dependent Claim
21 words
An optical system as defined in claim 3, wherein the holding means includes a resilient pad between the tube and connector.
Claim 9
Dependent Claim
99 words
An optical system, comprising: a light bulb including an elongate ionization tube having an opaque portion and a light transmitting portion, the opaque portion being substantially larger than the light transmitting portion, a light conductor extending generally laterally with respect to a side of the tube and having an end portion positioned in light receiving relationship with respect to the light transmitting portion, and resilient means extending at least partially about the ionization tube and including a connector for removably holding the light transmitting portion of the ionization tube and the light conductor resiliently in contact with each other.
Claim 10
Dependent Claim
99 words
An optical system, comprising: a light bulb including an elongate ionization tube having an opaque portion and a light transmitting portion, the opaque portion being substantially larger than the light transmitting portion, a light conductor extending generally laterally with respect to a side of the tube and having an end portion positioned in light receiving relationship with respect to the light transmitting portion, and resilient means extending at least partially about the ionization tube and including a connector for removably holding the light transmitting portion of the ionization tube and the light conductor resiliently in contact with each other.
